The folks at Backyard Brains, a DIY-neurobiology project, made these pigment-producing cells in a dead squid pulse to the base beats of Cypress Hill’s “Insane in the Brain.” Go watch that thing right now.
Done? Wowed? Prepare to be more wowed: They did it by exploiting the fact that electrical current is key to both the actions of cells and the playing of mp3s. These pigmented cells, called chromatophores, are surrounded by muscle cells, and it’s by flexing these muscles that the squid reveals its colorful spots. By hooked up the nerve that sends the flexing orders to the wire of a set of earbuds, they got these amazing results.
